Lead acid batteries typically have coloumbic efficiencies of 85% and energy efficiencies in the order of 70%. Depending on which one of the above problems is of most concern for a particular application, appropriate modifications to the basic battery configuration improve battery performance.
Implementation of battery man-agement systems, a key component of every LIB system, could improve lead–acid battery operation, efficiency, and cycle life. Perhaps the best prospect for the unuti-lized potential of lead–acid batteries is elec-tric grid storage, for which the future market is estimated to be on the order of trillions of dollars.
A lead acid battery consists of electrodes of lead oxide and lead are immersed in a solution of weak sulfuric acid. Potential problems encountered in lead acid batteries include: Gassing: Evolution of hydrogen and oxygen gas. Gassing of the battery leads to safety problems and to water loss from the electrolyte.
Lead acid batteries typically have coulombic efficiencies of 85% and energy efficiencies in the order of 70%. Depending on which one of the above problems is of most concern for a particular application, appropriate modifications to the basic battery configuration improve battery performance.
One of the singular advantages of lead acid batteries is that they are the most commonly used form of battery for most rechargeable battery applications (for example, in starting car engines), and therefore have a well-established established, mature technology base.
The nominal capacity of sealed lead acid battery is calculated according to JIS C8702-1 Standard with using 20-hour discharge rate. For example, the capacity of WP5-12 battery is 5Ah, which means that when the battery is discharged with C20 rate, i.e., 0.25 amperes, the discharge time will be 20 hours.

I have looked at purchasing a small 4Ah 12V Pb battery, but I am hesitant, because I am unsure of what currents the battery may be able to supply. I know the battery is small, but I have a small budget (Got the HID bulbs for free off a friend), and I am OK with a 30 minute battery life, as that is the max time I will be using it.
